Off the line, the Bmw M4 hits 100 km/h in 4.19 s versus 4.82 s for the Bmw 840i xDrive. At this point, the Bmw M4 leads by 0.63 s and sits roughly 2 m ahead.
At 200 metres, the Bmw M4 is doing 155 km/h against 141 km/h for the Bmw 840i xDrive. The gap is 0.42 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M4 crosses the line in 12.23 s versus 13.06 s. The 0.83 s gap represents roughly 40 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M4 continues to build its lead. At 600 metres, it runs at 219 km/h versus 197 km/h. At 1,000 metres, the Bmw M4 finishes in 21.86 s versus 23.73 s, with a 1.87 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the Bmw M4 and the Bmw 840i xDrive are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.54 kg/hp vs 5.39 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.39 seconds. The 0.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
